About Blizzard Pack
Blizzard Pack is the winter holiday seasonal pack, available each December–January window. It holds two notable records among all Blooket packs: its Santa Claus Legendary at 1.0% is tied with Medieval's King and Autumn's Turkey for the best Legendary rate in the game, and its Chroma history includes 12 retired Chromas, more than any other pack.
The Chroma roster rotates each holiday season. Blizzard has retired five Snow Globe variants (2020–22), Frost Wreath, Tropical Globe, three Sweater Snowmen (2023), Holiday Elf (2024), and Cozy Baby Penguin (2024). As of December 2025, the two active Chromas are Peppermint Bark (0.03%) and Chilly Chameleon (0.02%). Snow Globe, formerly a Chroma, was moved to Uncommon rarity when retired, which is why it now appears in the Uncommon slot.
The current rates place five Uncommons at 14.5% each (72.5% total), four Rares at 5.55% each (22.2% total), Snowman Epic at 4.25%, Santa Claus Legendary at 1.0%, and the Chroma tier split between Peppermint Bark (0.03%) and Chilly Chameleon (0.02%) for 0.05% combined.
Blizzard Pack's annual Chroma retirement cycle makes it the pack with the deepest historical lore in the game. Retired Chromas like Snow Globe, Frost Wreath, and Tropical Globe are now unobtainable from any pack opening, giving them strong scarcity value in community trading. The four Rare slots at 5.55% each (22.2% total) give Blizzard a relatively Rare-friendly distribution compared to packs with fewer Rare slots, and the Snowman Epic at 4.25% offers above-average Epic frequency for the 25-token tier. The December-through-January window typically sees the highest token-saving urgency of any seasonal event, as Blizzard offers both the joint-best Legendary rate in the game and a rotating Chroma history that rewards long-term players.
How to chase this pack
Santa Claus at 1.0% is the best Legendary deal in the seasonal pool, about 69 packs (1,725 tokens) to reach 50% probability. That matches Medieval's King at a slightly higher per-pack cost but within the seasonal window constraint. Peppermint Bark at 0.03% requires ~2,310 packs; Chilly Chameleon at 0.02% requires ~3,466 packs. The seasonal window limits your open count, stockpile tokens before December and open aggressively during the event.
